Excadrill, the famed OU sand sweeper, can take on a different role in the Ubers metagame. Rapid Spinners are in short supply in Ubers, and Excadrill is the only viable offensive Rapid Spinner in the metagame! Because many teams carry both Groudon and Kyogre, Tyranitar's sandstorm can be harder to keep up, thus, Excadrill takes a different approach to its Rapid Spinning. Instead of focusing on becoming a speed demon in the sand, Excadrill beefs up its defenses for the purpose of being used on a rain team. Excadrill's Ground typing is a godsend to many rain teams, allowing it to be the only Rapid Spinner in Ubers that can switch into Thunders and most of all, Zekrom's Bolt Strikes.
Don't be fooled by Excadrill's subpar looking defensive stats, its 110 HP makes it far bulkier than it looks. In fact, this Excadrill takes special hits better than specially defensive Forretress, allowing Excadrill to easily switch into the infestation of Choice Scarfed Dragons! The special bulk of this set also allows Excadrill to never be 2HKOed by Palkia and Dialga's Fire Blast in the rain as long as they are not carrying Choice Specs. Additonally, Excadrill's great typing and offenses allows it to check many threats that Forretress and Tentacruel have serious issues with, such as Bulk Up Dialga, Calm Mind Steel Arceus, Dark Arceus, and most Electric Arceus. Excadrill also has a good chance of defeating Giratina-O, the most common spinblocker in Ubers. After a Swords Dance, Rock Slide will 3HKO most Giratina-O, while Giratina-O's Hidden Power Fire will deal paltry damage in the rain. If you want to destroy Giratina-O faster, you can use Shadow Claw over Rock Slide, which will 2HKO Giratina-O after a Swords Dance.
While this set may focus on rain support, Excadrill will still appreciate Tyranitar's Sand Stream. Not only does this turn Excadrill into a threatening sweeper, but it also allows Excadrill to outspeed and 2HKO Ghost Arceus with a +2 Earthquake, while Ghost Arceus will fail to KO Excadrill with Focus Blast. If you wish take advantage of Excadrill's ability, a spread of 64 HP / 252 SpD / 192 Spe can be used to outspeed Choice Scarf Terrakion in the sand while still letting Excadrill have a decent amount of bulk. While Excadrill may focus on bulk in Ubers, it is also capable of using its OU sweeping set to great success in Ubers. Once Groudon and Kyogre are out of the way so Tyranitar can bring up the sand, Life Orb Excadrill is a monstrous sweeper in Ubers, being able to OHKO bulky Pokemon such as Arceus after a Swords Dance!
